摘要： The invention relates to a device (1) for the variable setting of the control times of gas-exchange valves of an internal combustion engine, with a driving element (12), with a driven element (8) and with an adjusting gear (11) designed as a triple-shaft gear, the driving element (12) being mounted rotatably with respect to the driven element (8) on the latter or on the camshaft (9). The relative phase position of the driven element (8) with respect to the driving element (12) can be selectively varied or held by means of the adjusting gear (11). According to the invention, it is proposed to mount the driving element (12) on the driven element (8) by means of rolling bearings (19, 21).Radial and/or axial forces can thereby be supported in an optimized way in terms of friction, as a result of which the efficiency of the device (1) is increased.

摘要： A hydraulic camshaft-adjusting device of the rotary piston type that includes of a drive gear (2) directly connected to a crankshaft and an impeller that is directly connected to a camshaft (3). The drive gear (2) has a cavity formed from a perimeter wall (5) and two side walls (5, 6) inside of which at least one hydraulic working chamber is formed from at least two boundary walls. The impeller has at least one radial vane (12) and each vane (12) divides one hydraulic work chamber into two hydraulic pressure chambers. The outer end (18) of each vane (12) of the impeller is pressed radially against the perimeter wall (5) of the drive gear (2) as a result of the force of a spring element (17) located at the inner end (15) of the vane. The spring elements (17) located at the inner end (15) of the vanes (12) have, at unchanged space requirements, a spring force that is greater than the pressure force of the hydraulic pressure medium acting on the outer end (18) of the vanes (12) in the respective actuated pressure chamber of the device (1).

摘要： An electromagnet having a hollow cylindrical coil former fitted with a coil winding and surrounded by a magnet housing. The coil former is bounded by upper and lower pole shoes. A nonmagnetic metal tube in the hollow cylinder of the magnet defines an armature space for a magnet armature that divides the armature space into first and second chambers, which are connected via a pressure equalizing channel in the magnet armature. A push rod passes through an axial hole in the lower pole shoe, to a control piston of a hydraulic valve, whose interior is connected via a further pressure equalizing channel in the lower pole shoe to the first chamber of the armature space. The push rod is a profiled rod contacting the magnet armature, the rod is of a cross-sectional shape different than that of the axial hole in the lower pole shoe and of a cross-sectional area less than that of the axial hole. The magnet armature has a central longitudinal hole of a diameter smaller than the largest profile width and larger than the smallest profile width of the push rod.
